Something happening with Message system and order Delivery Option,

Hi All,
I noticed since new text writing tools introduced, its more user friendly and very easy to write and modify, Loved it,
The problem i noticed is, sometime after writing a text to a buyer and when i hit submit the page reloads and the message disappeared and nothing has been submitted, still blank everything,

Problem in delivery option, I used to delivery with my custom designed delivery picture, Today i uploaded the picture several time, its just disappeared, and leave that place blank, picture added bellow,

Is anybody is facing same issues? also i want to know if you could reach support team in last 24 hours,
Regards
